Exploring the infinite wonders of theoretical physics while embracing life’s
enigmatic beauty. Passionate about unraveling the fundamentals of the universe
and the intricate stories it holds.

My current research delves into the intriguing intersection of quantum gravity
(QG) and particle physics, with a particular emphasis on unraveling the
gravitational effects Beyond the Standard Model (BSM) — notably within the Higgs
sector.

In the quest for new physics beyond the Standard Model, the Higgs sector stands
as a potential gateway to understanding higher-scale phenomena. I believe that
advancing field theories under the influence of gravity is crucial for studying
BSM physics and unlocking the secrets that lie beyond our current understanding.

    All possible theories of quantum gravity suggest the existence of a minimal
    length. As a consequence, the usual Heisenberg uncertainty principle (HUP)
    is replaced by a more general uncertainty principle known as the generalized
    uncertainty principle (GUP). The dynamics of all quantum mechanical system
    gets modified due to GUP. In this work, we consider both Einstein’s and
    Debye’s models to find the quantum gravity effect on the specific heat of
    solids. GUP modified specific heat in Einstein’s model shows usual
    exponential dominance at low temperatures. Further, the modification to
    Debye’s specific heat is calculated by considering the GUP modified
    dispersion relation, which becomes time dependent for elastic waves.
